How to turn off fast charging on Xiaomi Redmi Note 10: all the ways and consequences

Xiaomi Redmi Note 10 is one of the most popular mid-range smartphones, known for its balance of performance and autonomy. However, the fast charging feature, despite its convenience, can negatively affect battery life. Many users want to turn it off to reduce battery heat and extend its life. But how do you do it right?

In this article, we’ll take a look at all the available ways to turn off fast charging on the Redmi Note 10, from standard settings to hidden features in the engineering menu, and learn about the risks associated with changing charging settings and how to avoid common errors. If you notice that your smartphone is getting too hot while charging or the battery is losing capacity quickly, this guide will help you optimize the process.

It is important to understand that the manufacturer does not always provide a direct option to disable fast charging via the MIUI interface. So some methods will require additional manipulation or even root rights. We will consider options for users with different levels of training, from beginners to experienced enthusiasts.

Why users want to turn off fast charging on the Redmi Note 10

Fast Charging technology has become the standard for modern smartphones, including the Redmi Note 10 lineup, which allows you to restore battery power in minutes, but this convenience has the flip side.

• 🔥 Overheating of the device - with rapid charging, the body temperature can rise to 40-45°C, which is uncomfortable when used and potentially harmful to internal components.
• 📉 Battery degradation – Lithium-ion batteries wear out faster at high charging currents.Switching off Fast Charging could extend lifespan by 15-20%.
• ⚡ Unstable power supply – in some regions, power surges in the network can lead to failures during fast charging, which can damage the power controller.
• 🛌 Night charging – leaving your smartphone on charge all night with fast charging on is not recommended due to the risk of overheating.

Manufacturers, including Xiaomi, often don’t advertise the ability to turn off fast charging, because it’s a marketing advantage, but in some MIUI firmware (especially global versions), the option is hidden in the depths of the menu, and if it’s not, you’ll have to use workarounds.

⚠️ Warning: Turning off fast charging does not guarantee 100% battery protection, wear and tear is also affected by discharge cycles, ambient temperature and charger quality. If you use non-original power supplies, the risk of battery degradation increases significantly.

Method 1: Disconnect via standard MIUI settings

The easiest and safest method is to use the built-in MIUI options. Unfortunately, not all versions of the firmware for the Redmi Note 10 are available, but it is worth checking.

1. Open the Settings app (cog icon).
2. Go to the Battery and Performance section.
3. Select Charge or Charge Settings (the name may vary depending on the MIUI version).
4. Look for the option Fast Charging – if you have one, move the slider to the off position.

If there is no such item, try an alternative path:

1. Go to Settings → Additional → Special Opportunities.
2. Find the Battery Optimization section.
3. In some firmware here is hidden the option to Limit the charging current.

On the Redmi Note 10 with global firmware (e.g. MIUI 12.5 or 13), this works 60-70% of the time. If you have a Chinese version of MIUI, the odds are lower – the manufacturer often removes such settings for the local market.

Check the version of MIUI in Settings → About the phone

Use the original cable and power supply

Charge your phone to 30-50% before experimenting

Make a backup copy of important data-->

⚠️ Note: Once you turn off fast charging via settings, your smartphone can automatically return it after you restart, due to Xiaomi’s energy saving policy. To fix the changes, you will have to use one of the alternative methods (see the following sections).

Method 2: Use the engineering menu (code ##4636##)

If standard settings don’t work, you can try turning off fast charging via the engineering menu, which works on most Xiaomi devices, but you need to be careful – wrong actions can disrupt the stability of the system.

Instructions:

1. Open the Phone app and enter the combination: ##4636##.
2. You will be taken to the Testing menu. Select the Battery Information tab.
3. Scroll down to the Charging section, and you can see current and voltage settings here.
4. Look for the Fast Charge or Quick Charge option. If it's active, try clicking on it to turn it off.

Note that some versions of MIUI may have their engineering menu blocked or not contain the necessary options, so try the alternative code:

##6484##

This code opens the MTK Engineer Mode menu (for devices on MediaTek chipsets, which include the Redmi Note 10 with a Snapdragon 678 processor is not suitable).If your smartphone on Qualcomm, try:

##7378423##

If the engineering menu doesn’t give you the ability to turn off fast charging, don’t despair – in the next section we’ll look at a more reliable method using ADB.

Method 3: Disconnect via ADB (for power users)

If previous methods didn't work, the most reliable way is to use Android Debug Bridge (ADB), a debugging tool that lets you change system settings through your computer, and the advantage of the method is that the changes will persist even after you reboot.

What you'll need:

• 💻 Computer with Windows, macOS or Linux.
• 📱 USB-cable (preferably original).
• 🔧 Installed Xiaomi drivers and package ADB Tools.
• 🔓 Included debugging by USB smartphone.

Step-by-step:

1. Activate Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI Version until you become a developer!

Settings → Additional → For Developers

• USB debugging
• Unlocking OEM (if any)
• Connect your smartphone to your computer and confirm your trust in the device.
• Open the command line (or Terminal) macOS/Linux) Enter: adb shell settings put global fast_charge 0 This command disables fast charging at system level.
• Restart your phone to apply the changes.

To return fast charging, use the same command, but with a 1: setting.

adb shell settings put global fast_charge 1

⚠️ Note: Some Xiaomi firmware may be ignored ADB-If the fast charge is still active after the command is executed and the reboot, then your version of the charge is still active. MIUI In this case, only obtaining root rights will help (see the next section).

💡

Before using ADB, check if your Redmi Note 10 is recognized on the system. To do this, type in the adb device command — if the device is displayed, you can continue. If not, install Xiaomi USB Drivers or use the universal Google USB Drivers.

Method 4: Disable fast charging with root rights

If all the previous methods didn't work, the last option is rooting and editing system files, which is the most radical way, which gives you complete control over charging, but has risks:

• 🚨 Loss of warranty (if the device is under warranty).
• 🔐 Risk of “bricking” of the smartphone with incorrect actions.
• 🛡️ Vulnerability to malware (root opens access to system files).

If you are willing to do this, follow the instructions:

1. Unlock the bootloader through the official Xiaomi website (requires a Mi Account and wait 7-15 days).
2. Install custom recovery (such as TWRP) for your Redmi Note 10 model.
3. Please use Magisk to obtain root rights.
4. Download a charging control app, such as AccuBattery (allows you to limit charging current), Kernel Adiutor (for fine-tuning the kernel), Fast Charge Switcher (directly disabling Fast Charge).

In the app, find the option to turn off fast charging and apply the changes.

Once you get root, you can also manually edit the file. /sys/class/power_supply/battery/input_suspend, signify 1 (It turns off fast charging. But it requires knowledge of how to work with ADB Shell or terminal in TWRP.

💡

Getting root rights is a last resort. If you are not sure of your skills, it is better to focus on the ADB method or use third-party applications without root (for example, AccuBattery for monitoring current).

What to do if nothing helps: alternative solutions

If none of the above methods worked, don’t despair. There are several workarounds that can help reduce the negative impact of fast charging on the battery:

• 🔌 Use a charger with less power — instead of the original 33W unit, take a 10-18W charge (like an old smartphone.
• 📴 Turn off the smartphone while charging – when switched off, the Redmi Note 10 charges slower and heats less.
• 🌡️ Control the temperature if the phone is over 35°C, interrupt the charger and let it cool. Use applications like AIDA64 monitor.
• 🔋 Limit the charge to 80% – in some firmware battery settings there is an option Optimized charging, which stops charging by 80%, extending the battery life.

You can also consider buying a power bank with support for slow charging, such as external 5W/1A batteries that will charge the Redmi Note 10 in a gentle mode, and the main thing is to avoid cheap Chinese charging of unknown brands that can damage the power controller.

Important: If your Redmi Note 10 is warming up even when charging normally, the problem may not be with the Fast Charging, but with a faulty battery or controller, in which case it is recommended to contact a service center for diagnosis.

Risks and consequences of shutting down fast charging

Before deciding to disable Fast Charging, it’s worth weighing the pros and cons. Here are the consequences:

• ⏳ Increase charging time – instead of 1-1.5 hours to 100%, you will need 2.5-3 hours.
• 📱 Less heating of the body - the temperature during charging will decrease by 5-10°C.
• 📊 Potential increase in battery life – if properly operated, the battery can last 200 to 300 cycles longer.
• ⚡ Risk of unstable work – if you have used it ADB or root, there may be failures in the power controller (rarely).

Also, keep in mind that turning off fast charging does not reverse other battery degradation factors:

• Deep discharges (below 10%).
• Long-term storage with full charge (100%).
• Extreme temperatures (below 0°C or above 40°C)

If you decide to disable Fast Charging, we recommend combining this with other battery-saving measures:

• Use the Dark Theme to reduce the load on the screen.
• Turn off 5G and NFC if you don't need them.
• Follow the background processes through Settings → Battery → Battery use.

💡

For maximum effect, combine fast charging shutdown with a maximum charge limit of 80-85%, which can be done through applications like AccuBattery (without root) or Battery Charge Limit (with root).
